Use C++ with Objective-C in XCode
- by prosseek
I want to use/reuse C++ object with Objective-C.
I have a hello.h that has the class definition, and hello.cpp for class implementation.
class Hello
{ int getX() ... };
And I use this class in Objective-C function.
#include "hello.h"
...
- (IBAction) adderTwo:(id)sender
{
Hello *hi = new Hello();
int value = hi->getX();
NSLog(@"Hello %d", value);
[textField setIntValue:value];
When I compile the code in Xcode, I get this error message.
class Hello *XXXXX
Users/smcho/Desktop/cocoa/adderTwo/hello.h:9:0
/Users/smcho/Desktop/cocoa/adderTwo/hello.h:9:
error: expected '=', ',', ';', 'asm' or '__attribute__' before 'Hello'
Q: What went wrong? Am I missing something?
